What psi do ya'll run in the tires?

[rammertide07]

Any Snap Line chalk works well

You mean like just get the bottle of powder, poor it on top of the tire, and rub it in?

My tires are D range- 8 ply- LT315/75/16 A/T- Load index 121 (3197lbs)- Speed rating Q (99mph).

Side wall says 50 psi cold. So with the outside temp being in the 90's.....???

Load index for the tires is 3197lbs. If that is per tire then thats a total of 12,788lbs spread out across all the tires...if that is a correct method. I can understand possibly being underated when pulling my 5th wheel. [I just dont know how much more weight is being put down on my bed.] I've only pulled it once....75mph for 4hrs.

Any suggestions on 10ply A/T's?

[thats where a CAT Scale comes in] Truck alone: Front & Rear Axel Weight. Truck & 5r: Front/Rear Axel weight of the truck (dif on the rear, as compared, being.. the Pin weight) plus... the Axel weight on the 5r.. for a total GVW of the whole works ?

Good info to have & know, for tire pressures all 'round.

Nope.. spread a little of the chalk on a smooth surface.. drive the truck thru it, note the chalk marks on Each tire when it's visable.. repete that while increasing or decreasing psi 'til you get about a 1/2" of CLEAN tire, on the outside edges of Each tire.

Note the PSI then with a good gauge. Time consuming, but worth the effort.

Yea...I just dob't have access to a CAT scale. Sometimes I see the big rig scales at SOME truck stops, but I dont even remember the last time I've seen a truck stop with one.

chalk is chalk. i would not use powdered chalk i think. i would rather mark the tires and then drive.

bue railroad chalk in landscape supply? blackboard chalk? drug store/toy store in the kids section look for sidewalk chalk.
